The invention is directed to performing electronic component mounting operations by the suction nozzles of the mounting heads in each of the plurality of the rotary tables independently, moving each of the positioning tables for positioning a printed board in a component mounting position independently, and performing the electronic component mounting operation on the plurality of the printed boards independently. A component feeding device moves a plurality of component feeding tables having a plurality of component feeding units in an arraying direction thereof respectively and independently. Mounting heads having a plurality of suction nozzles for picking up electronic components from the component feeding devices respectively are provided at predetermined intervals corresponding to intermittent pitches on an outer circumference of two rotary tables intermittently rotating. Therefore, the suction nozzle of the mounting head of each of the rotary tables picks up the electronic component fed to a component pickup position in each of the component feeding units set on each of the component feeding tables, and mounts the component on the printed board on the corresponding XY table.

Apparatus for feeding electronic components comprises a slide base, a plurality of tape cassettes mounted on the slide base, a linear motor 14, and a control unit for the motor. The control unit includes a motor driver 61, a memory device 66, and a control device 67 which controls the motor driver 61 using data stored in the memory device 66. The control device 67 adjusts the data for controlling the motor according to the load weight of the slide base. The data is used for properly moving the slide base carrying a plurality of tape cassettes to a position for feeding the components.

Technology is provided for changing a mounting angle of a component to reduce the amount of relative displacement between a mounting head and a board. A component, for which a mounting angle can be changed, is specified based on information stored in a mounting data storage area and a component data storage area according to a predetermined component mounting order. A mounting time in a mounting path with the mounting angle of the specified component being changed is calculated for each mounting angle to specify the mounting path requiring the shortest mounting time.

This invention is directed to the prevention of the deterioration of the accuracy in component mounting by suppressing the temperature rise of the moving member as much as possible by cooling the moving member, which is the heat source of a linear motor. The moving member 48 of the linear motor 14 is configured in the following manner for achieving the objective of this invention. That is, the heat dissipation portion, the axis 17 made of the material with efficient thermal conduction such as aluminum, pierces through the iron core 18 around which coils 20 are wound. The moving member except a part of the axis 17 is molded with synthetic resin, and at one end of the axis 17, the heat dissipation fin 19 which makes heat dissipation area larger is formed. And this heat dissipation fin 19 is placed to face the air exhaust port 67. By configuring the moving member in aforementioned manner, the temperature rise is suppressed even if the coils 20 generate heat, because the heat in the coils 20 is transmitted to the iron core 18 and then to the axis 17 and dissipated through the heat dissipation fin 19. The heat in the outermost part of the iron core 18 from the heat dissipation fin 19 is also transmitted to the heat dissipation fin 19 through the axis 17 resulting in the suppression of the temperature rise of the moving member as a whole.

摘要:
When manufacturing an optical recording medium by forming a resin layer on a surface of a substrate and then forming a center hole that passes through the substrate and the resin layer, a method of manufacturing an optical recording medium according to the present invention forms the center hole by forming, in the resin layer, a circular cut with a larger diameter than the center hole so as to surround a formation position of the center hole and then pressing in a punching blade for forming the center hole from a rear surface side of the substrate. By doing so, detachment of the resin layer and the production of burrs at or near the center hole can be avoided while reducing the manufacturing cost.
